Vintage Reel to Reel Recorders. Restored, hopefully, to a factory specification or as close as was possible. I occasionally offer some recorders for sale, those that I have more then one or two off, but more then happy to swap for something I have not got in my collection yet, though this is quite difficult, as I have more then one hundred just in one room.
Because aesthetics are very important for me, I am now indulging in collecting used aluminium reels, mainly old Ampex and Zonal and some get anodized, others get powder coated or wet painted. This, of course, is a bit like with Marmite - you love it or you hate it. It was very difficult process, surprisingly, to put together a team that can do a dissent quality of workmanship, but I do think we have got it "all in place" now.
All the descriptions offered with machines on You Tube, are to "my best knowledge" and I do not wish to get entangled in arguments over small and unimportant details. Information is not easy to come by.
